by the provision of a verticallymovable roll which is adapted tocompress the yarn in the various packages as it is wound and to also maintain each yarn in the position in which it is laid by the movement of atraversing member. Inthe above described patented arrangement, the whole traversing mechaa nismis supported by the pressure roll and therefore moves vertically as the yarn packages .increase in diameter beneath the pressure roll, and it is one of the objects of the present invention to provide an improved package forming machine "in which the necessity for permitting vertical movement of thetravers ing mechanism with its-associated binding I v r second roll,5.';The yarn 3 is thenled uproll is eliminated.

According to the present invention we provide an improved arrangement in which the separate yarns are led to'the package carrying shaft by a traversing] mechanism which is adapted for a reciprocatory movement only, and is not capable of vertical movement with respect toithe package shaft. Further morefthe separate yarns are led around a rotatably driven friction roll on which the;- package forming shaft bears, so that this roll serves the double function ofdriving the package shaft to wind the packages and of providing sufficient pressure between each package and the'roll to maintainthe'yarn in the position in which it is laid by move mentof the traversing mechanism. As a result, our improved machine is muchsimpler in construction and more convenient to operate than machines of the type shown inthe aforesaid Patent No. 1,503,381. Additionalr advantageous features of our invention will hereinafter more fullyv appear from'the following detailed description, taken in connecsection.

Yarn 3 for forming the packages is, led from a suitable source such as a creel, not shown, to-the front of the machinewhere itpasses over aroll 4 carried between vertical extensions 1a of the frame 1 and then I downwardly around. a

guide rolls 6 corresponding in number to the number of package-forming mechanisms, one, ,of which will next be described. i

.The sideframes 2 carry a number of pair 7 As shown at the right'in Fig.1, the shaft 9 ,when empty isv adapted torest in engage ment with the periphery of a roll11 havinga frictionalsurface, the ends 'of which are receivediir bearing blocks 12 also slidable within the slots 8. The end portions of the shaft lladjacent the bearing blocks 12 bear on a pair of friction discs 13 mounted on a shaft 14 extending between theside frames 2 "and:journalled-therein.a As best shown in Fig.2 the shaft Myextends' beyond the side frames 2 and carries at one end a bevel gear in mesh with a bevel gear 16 carried on a shaft 17 extending the length of the machine. a cross shaft 18 through gearing 19, the cross shaft 18 being'j'ournalled below' the i .frame extension la and carrying a pulley 2O adapted to drive the roll'11 in engagement by means of which the shaft 18'may vbe driven from a suitable source of power, not shoW111 I When the shaft 17 is driven as described above, all of the shafts'14 are driven in unison and each pair of friction discs 13 are therewith, leaving the ro ll 11' free. between the friction discs 13 combinedfweight of a package shaft "9 and its associated roll 11 is suflicient to cause the necessary frictional engagement betweenthe surfaces.- Rotation of each shaft 14-is also depended upon to drive the traversing mechanism that is emj ployed in connection with each package shaft 9 to deliver the several ends of yarnto the shaft 9 with. a traversing movement for the formation of'separate packages thereon. v To 7 this end, the right-hand end of each shaft 14 carries a spur gear 21 in mesh'with a gear 22 mounted on a shortshaft 23, the shaft 23 also carrying a traverse cylinder 24, the surface" of which provides a splral groove 25, over which extends a traversebar'26. ,As best shown in Fig.2, the traverse bar 26 is slidablymounted ing'uides 27 provided by the side frames'2, the end of the bar 26 extend-- 'ing over the surface of the cylinder 24 carrying a roll 28 received in the groove 25. g'ljhe groove 25'is so formedthat one revolution of the shaft 23 is adapted'to impart a com- 7 plete back and forth movement to thejtraverse I bar 26, the amplitude of "this 'movement being dependent upon the'pitch ofthe groove 25. The'traverse bar25 has connected'there' to a number of arms 29, each pivoted at 30. 5 l and providing ,a'slot 131'f0r receiving one rof-several pins 32 carried by'the traverse -45.

the bar 26 causes the arms 29' to swing in '-unis'on.q-

The yarn 3Vpasses upwardly around the roll 11, and

When a shaft 14 is driven as previously dc scribed, the friction discs 13 W111 .drive the 2 roll 11 and shaft 9 in unison but in Opposite directions, at the same time a setfof fingers '34 carriedbythe traverse bar 26will deliver several ends of yarn 3 to-the-shaft 9 with a traversing movement. vAs a result,'the yarn 3 ,will bewound on the shaft 9 in separate packages, the width of which will be deter-V mined by the amplitude of the movement of the traverse bar 26'. As an end of yarn- 3 is moved back and forthon the roll 11, the pre ssure eXerted betweenthe roll'11 and the shaft 9 at the point where the yarn passes onto the shaft 9, or the package, will serve to maintain the yarn in the position in which it is laid by movement of the traverse bar;26,

After the yarn packages have been completely.formed'onthe shaft 9,:the pressure roll 35-may be conveniently raised above the yarn'lpackages, as indicated in Fig; 1, by 2 means of'hand wheels 37 provided at theiends I of a shaft 38 extending between the standards 7 behind the pressureroll 35 As shown in Fig; 4, the shaft38 is mounted in'brackets 39 extending'ffrfom the bearing blocks '36 and' apair of pinion's-4O are also mounted on the shaft 138 in engagement with teeth41 provided-on the rearface ofeachstandard 7 1 By turning either one of'thezhand wheels 37, the roll 35 can be raised on the standards 7 and, if desired, "therentire pressureroll assembly can'be locked in its raised position by means of pawls 42 adapted to be'turned intoeng'agement with the" teeth 41. When a pressure roll 35' has been raised and locked a in its upper position, as indicated, it is. p'ossible to readily reniove'a shaft 9 with the completed yarn packages thereon by lifting the same until the reduced ends 10'of't he shaft 9 ,come into register with oppositely disposed. alined notches 43 provided in the front faces 'of the standards? "and opening into the slots 8 in which the ends'IQ. of the shaft, 9-are slid- From the foregoing, it that V J our-invention we have provided an improved;

machine for forming yarn packages, that is and effective traversing mechanism. The

fact that the yarn deliveri'ng fingers 34 are mounted for pivotal movement only, enables the who'le traversing mechanism to be dis- 12 5" particularly characterized by a'very'simple posed below the shaft '9 on which thepackages are formed. This permits ready inspec tion of thepackages at all times, there being no mechanism whatsoever disposed in the space in front of, ing formed. The having the combined function of both frictionally driving the package shaft 9 andholding'e'ach yarn end at the point at which it is laid by its traverse finger is also believed to be an improvement over previous machines of this type.
